# FBDASH - lightweight dashboard for the RaspberryPi without X (using framebuffer only)
|
|
In order to setup the dashboard start with cloning this repo ;)
|
|
git clone https://git.klelifo.de/flo/fb-dash
|
|
cd fb-dash
|
|
|
|
|
|
|
|
# Configure the display
|
|
**TL;DR** just run ```make rpi-config```
|
|
|
|
Some work is needed before we can actually use the ILI9341 display with the RaspberryPi.\
|
|
Essentially we need to
|
|
* Enable the SPI interface
|
|
* Load the fbtft_device kernel module with the correct parameters
|
|
to get a working /dev/fb1 framebuffer device.
|
|
|
|
## Enable SPI interface on the raspberry pi
|
|
echo "dtparam=spi=on" | sudo tee -a /boot/config
|
|
|
|
## Activate modules to be loaded at boot
|
|
echo "spi_bcm2835" | sudo tee -a /etc/modules
|
|
echo "fbtft_device" | sudo tee -a /etc/modules
|
|
echo "options fbtft_device name=rpi-display gpios=reset:25,dc:24,led:18" | sudo tee -a /etc/modprobe.d/fbtft_device.conf
|
|
|
|
|
|
|
|
|
|
# Setup fbdash binary
|
|
***TL;DR** just run ```sudo apt install -y libmariadb2 && make install```
|
|
|
|
After the display is setup we can build and install the fbdash binary.
|
|
|
|
## Build the sources
|
|
sudo apt install libmariadb2
|
|
make
|
|
|
|
## Install in /usr/bin
|
|
sudo make install
|
|
|
|
## Test it
|
|
fbdash
|
|
|
|
|
|
|
|
# Use systemd for regular updates
|
|
While we could also use cron for regular execution of the fbdash binary I opted to use systemd this time.\
|
|
The future is now ... ;)
|
|
|
|
## Install unit files
|
|
**TL;DR** just run ```make systemd-config```
|
|
|
|
The following files use systemd to setup a regular update of the dashboard screen (60s by default).\
|
|
If you like to change the default, just edit the ```fbdash.timer``` file before reloading systemctl
|
|
|
|
sudo cp setup/fbdash.service setup/fbdash.timer /etc/systemd/system
|
|
sudo systemctl daemon-reload
|
|
sudo systemctl enable fbdash.timer
|
|
sudo systemctl start fbdash.timer
|
|
|
|
## Check timers
|
|
systemctl list-timers
|
